Scientists have discovered a protein that seems to protect animals from cancer and other deficiencies of old age, with no downsides. The research on protein BubR1 could offer clues on how protecting chromosomes can enhance health.

Sequencing DNA is nothing new, but it’s much harder to sequence the DNA of a single cell. In order to get enough DNA for sequencing, usually thousands or millions of cells are required. Finding out which mutations are in which cells is extremely difficult, making the mutations present in only a few cells, like early cancerous cells, almost impossible to detect.

The fossil record gives clues about how limbs grew from fish fins in a series of stages, but scientists are still trying to fill in the details and determine what genetic changes might have allowed limbs to grow.

Australia’s Department of Agriculture announced that it is in the final stages of developing a new breed of pineapple that is sweet and juicy, but has the added taste of coconut, making it suitable for the for piña colada cocktails.
